Agent for imparting viscosity to liquid batter

Abstract

[Problem] To provide: a water-insoluble plant fibrous material derived from soybeans that has both the functions of imparting viscosity to liquid batter and of stabilizing viscosity; a method for imparting viscosity to liquid batter using said raw material; and a method for stabilizing viscosity. [Solution] The provision of an agent for imparting viscosity to liquid batter was achieved by using a water-insoluble plant fibrous raw material obtained by: heating a slurry, prepared by adding water to bean curd lees, to more than 100° C. and up to 150° C.; then substantially removing the water-soluble component thereof.

1 . An agent for imparting viscosity to a liquid batter, comprising a water-insoluble plant fiber material which is obtained by preparing a slurry by adding water to an okara, subjecting the obtained slurry to a heat treatment at a temperature higher than 100° C. and not higher than 150° C. and then substantially removing a water-soluble component. 
     
     
         2 . The agent for imparting viscosity to a liquid batter according to  claim 1 , wherein the time for the heat treatment is not less than 1 minute and not more than 360 minutes. 
     
     
         3 . The agent for imparting viscosity to a liquid batter according to  claim 1 , which comprises adding a metallic salt to the slurry. 
     
     
         4 . A liquid batter comprising the water-insoluble plant fiber material according to  claim 1 . 
     
     
         5 . A method for imparting viscosity to a liquid batter and a method for stabilizing viscosity of the liquid batter, comprising using the water-insoluble plant fiber material according to  claim 1 . 
     
     
         6 . The agent for imparting viscosity to a liquid batter according to  claim 2 , which comprises adding a metallic salt to the slurry. 
     
     
         7 . A liquid batter comprising the water-insoluble plant fiber material according to  claim 2 . 
     
     
         8 . A liquid batter comprising the water-insoluble plant fiber material according to  claim 3 . 
     
     
         9 . A liquid batter comprising the water-insoluble plant fiber material according to  claim 6 . 
     
     
         10 . A method for imparting viscosity to a liquid batter and a method for stabilizing viscosity of the liquid batter, comprising using the water-insoluble plant fiber material according to  claim 2 . 
     
     
         11 . A method for imparting viscosity to a liquid batter and a method for stabilizing viscosity of the liquid batter, comprising using the water-insoluble plant fiber material according to  claim 3 . 
     
     
         12 . A method for imparting viscosity to a liquid batter and a method for stabilizing viscosity of the liquid batter, comprising using the water-insoluble plant fiber material according to  claim 6 .
